A few years ago, we picked up A patient complained of hearing loss, pure tone audiometry is generally normal, but the patient is said to be inaudible, auditory brainstem response examination reveals post-cochlear lesions, and the head CT report is multiple sclerosis. At that time, we thought that the results of the morphological examination could not explain the results of the functional examination, which meant that multiple sclerosis did not cause hearing changes.
This shows that we have not enough understanding of the impact of multiple sclerosis on hearing function. With the accumulation of clinical experience and continuous observation and research, the hearing function of patients with multiple sclerosis is not changed. As rare as in previous textbooks, the literature also reported abnormalities in 60% of auditory brainstem responses in patients with multiple sclerosis.
Since the multiple sclerosis is caused by central hearing loss, the patient often complains about the sound, but can’t hear what others say.
